I have tried many times but it is not complete. Even I have seen how to do it on tube and reddit, it still doesn’t work
Possible fixes:
Play professional difficulty (master also works).
Don’t save and reload. (seems to break camera challenge)
If you fail the mission don’t load or replay. Instead exit to main menu then return.
A possible fix for (nightcrawler) challenge:
Make sure to stay as close to Omar as possible.
When he makes it to Carl Ingram’s office, if he says “He’s not here probably on a stroll.” Your camera challenge should work.
Try not to cut off their dialogue.
Make sure to wait until he’s fully on the bed.
Take a few photos. (Do not spam the camera it tends to glitch out the challenge)
